Jagged Alliance (PC, 1994)
Sadly it's a mixed bag. The game is very ambitious and innovative for its time, and I enjoyed the characters and managing my team a lot, but it's brutally hard with a fairly dated interface and a lot of downtime between its interesting parts in the form of inventory management and simply moving around the map.
Good: You get to hire and level up a squad of up to 8 mercs (out of 60 different ones, fully voiced and each with their own personality quirks affecting gameplay) which can be replaced at any point, as well as manage CPU controlled guards and workers in conquered territory to be able to fund your team. There are sidequests, some with alternate solutions and you can spy on enemy guards for clues to some of them using a probe. You get to choose which sector to attack, when and from which direction on the world map, and you can escape and re-enter battles as long as you can make it to the edge of the sector with a gathered party. There's a real time element in the form of a day/night cycle - you move out in the morning and need to make it back to a conquered sector before nighttime. If you're finished for the day or need to regain stamina (mercs will move slower and eventually collapse when it's drained), there's a fast forward option you can use outside of battle. Movement is also in real time outside of battle and you can move the entire squad at once like in an RTS, which is kind of neat for 1994. Another cool thing is that you need to use stealth to capture certain sectors with processing plants in them, which give a boost to your economy, or the enemy will blow the plant up with an in-battle soldier using a remote control. It's also not a huge setback if it does get blown up as it will eventually be repaired. Finally the ending can change depending on a couple of actions you take in-game.
Bad: Besides what I mentioned above, you pretty much need to read the manual thoroughly as well as watch part of some LP before playing or you'll probably walk into the game spending too much money, slowly killing everyone off and ending up having to restart after several hours of play. This is because the game can hit you with a lot of unexpected events early on, like your water supply getting poisoned and you having to figure out which sectors to conquer to fix this without much direction, or the CPU guards and workers (and even your mercs) suddenly quitting if you're not doing well enough.
In combat, the game can get annoyingly random by letting the enemy hit your mercs while you can't hit back even with great aiming skills and gear, and your guns also tend to get jammed for a few turns even in pretty good condition (almost everything deteriorates actually, but since you can leave a merc in the base to repair things it's not much of an issue except for the guns jamming). At other times, or after reloading the quicksave, everything might go your way instead. But in general the enemies have an easier time hitting than you do.
Speaking of the enemies, they have a tendency to start running away when low on HP, but never actually retreating from the sector, which can lead to drawn out segments of slowly chasing down the last enemy in a sector. This becomes really tedious with hurt mercs since they lose action points as they lose health, plus their move animation becomes much slower and can't be skipped. Sadly the fast forward option also can't be used to move faster during exploration, making you spend a lot more time with moving around the world map and collecting loot than you'd want to. There are other flaws about the interface that bothered me, but then again I'm picky about that stuff.
Finally I have to mention the swimming, which is a nightmare. If you do play the game, just avoid deep water if you can, as it's very likely that a merc will drown from a random snake attack while swimming just a short distance and it also takes a toll on your gear. It helps to bring a knife for the merc to fight the snake with, but you'll still have to watch a slow animation and will lose a bunch of health and stamina from it. You also can't send someone else in to help the merc from drowning, other than giving them bottled water with which to replenish some stamina.
That got much longer than I intended, but there's a lot to the game that one probably won't catch on first glance. :)
The sequel seems a lot better, and has some mod support. Which I might have to start experimenting with as the original GOG version apparently doesn't work on my Windows 10 PC.
